Filed: 1987-09-04
Abstract: PURPOSE:To prevent generation of crack, breakage, and exfoliation of a ceramic body due to thermal stress when a ceramic body is bonded to a mother material interposing an intermediate material by setting backward an edge of the intermediate material from the ceramic side to the mother material side gradually. CONSTITUTION:A ceramic small piece 1 is bonded to a mother material 3 of a partner member interposing an intermediate material 2. In this case, an edge 2a of the intermediate material 2 is set backward gradually to the inner side than the edge 1a of the small ceramic piece 1 as the edge 2a of the intermediate material 2 is apart further from the small ceramic piece 1 side toward the mother material 3 side.

IPC: G11B21/12
Filed: 1989-08-31
Abstract: PURPOSE:To prevent attraction between a head slider and a disk by providing a cushioning material abutted with a suspension spring when no piezoelectric element is driven and separated from the suspension spring by driving the piezoelectric element. CONSTITUTION:A voltage is applied to the piezoelectric element 5 after the driving speed of a disk 50 arrives at constant speed. When the voltage is applied to the element 5, the displacement of the tip of the element 5 in a direction to be separated from the suspension spring 3 is generated, and as a result, the spring flexed in advance intends to recover to a flat state. When the spring 3 approaches the flat state, a slider 1 joined to the tip of the spring via a gimbal spring 2 approaches the surface of the disk 50, and is loaded on the disk smoothly. By flexing the element 5 further, the cushioning material 6 is completely separated from the spring 3, and no influence of the element 5 is given on the spring 3. In such a way, it is possible to always keep a non-contact state between the disk 50 and a magnetic head.
